Health Insurer Business Information Model

A health plan runs on member, provider, plan, and claims data — and the Health Insurer Business Information Model maps those data entities into foundational, transactional, and informational layers, delivered as an editable Word document you can adapt to your organization.

Why This Isn't a Generic Insurance Model

A health plan's data model breaks the moment you treat "Member" the way a generic template treats "Customer." The Subscriber who holds the policy, the Dependents covered under it, and the Member as the unit of enrollment are related but distinct entities whose relationships shift with life events — a dependent aging off at 26, a divorce splitting coverage, a newborn added mid-year. Layer in that a Member enrolls in a specific Plan under a specific Group (the employer), often with rating and benefits that vary by class within that same group, and "enrollment" stops being a single foreign key. Providers add another wrinkle: the same practitioner can bill under a group NPI or an individual NPI, sit inside multiple overlapping Networks, and change contracted status mid-year — a many-to-many relationship generic models flatten into one field. And Accumulators — the running deductible and out-of-pocket balances that determine what a claim actually pays — behave like stateful ledgers tied to plan year and individual-versus-family limits, not static attributes on a claim.

What's Inside

• Foundational entities — Member, Subscriber, Group, Provider, Plan, Network, Benefit
• Transactional entities — Enrollment, Claim, Authorization, Premium Billing, Accumulator
• Informational entities — Utilization, Risk Score, Quality Measure, Medical Loss Ratio Reporting
• Logical relationships and cardinality between every entity in the model
• Fully editable Word document

How Teams Use It

• Baseline for master data management programs spanning member, provider, and plan data
• Reference model for claims and eligibility system integration projects
• Input to data warehouse and application design for analytics and reporting
• Common vocabulary for data governance discussions between IT and health plan operations

Who It's For

Data architects, business architects, and IT leaders at health insurers, TPAs, and health tech vendors who need a sector-accurate starting point for data architecture, integration, or MDM initiatives — without spending weeks reverse-engineering entity relationships from claims and eligibility feeds.
